At this point someone just needs to call out most these devs on the fact that the only reason they don't want to make apps for WP8 is mostly BS politics. Just look at the tech press these days- so much biased reporting and anti-MS/WP hate from ****** bloggers and journalists (cnet, verge, engadget being some of the biggest offenders). Some are even outwardly hostile like Google (refusing to make official apps, blocking MS's youtube app, delaying release of ad mob sdk for WP8 devs for several months). Isn't it safe to assume that many Devs operate in the same way after 3 years on the market? MS has gone out of its way to make app development simple enough, even to the point where you can easily make an app available on Win8, WinRT, and WP8 with some minor adjustments (3rd party developers are able to create better looking/functioning apps than official versions as well). Multiple studies have shown that WP8 customers spend more on apps than more frugal Android customers as well. Plus WP has shown positive growth year over year. So the same excuses of market share, profitability, and difficulty to develop for are really flimsy when used over and over. Even Android gets put on the backburner as well, despite it having a massively larger market share than iOS.
I've only seen 1 dev provide a legitimate excuse for not having an app out, and that was snapchat under the reason they needed an API that would be in GDR3 in order to provide the same level of privacy as iOS and Android (preventing screenshots being taken). If one man (Rudy) can create an awesome 3rd party instagram and vine app, why is it so hard for all these other devs and companies- many that make 10's of millions to billions a year in profit- to assign even a few measly interns to write or port their apps to WP?
Just professional trolling and fanboys at this point from most these guys.
